26/* bfd.h -- The only header file required by users of the bfd library
27
28The bfd.h file is generated from bfd-in.h and various .c files; if you
29change it, your changes will probably be lost.
30
31All the prototypes and definitions following the comment "THE FOLLOWING
32IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
33BFD. If you change it, someone oneday will extract it from the source
34again, and your changes will be lost. To save yourself from this bind,
35change the definitions in the source in the bfd directory. Type "make
36docs" and then "make headers" in that directory, and magically this file
37will change to reflect your changes.
38
39If you don't have the tools to perform the extraction, then you are
40safe from someone on your system trampling over your header files.
41You should still maintain the equivalence between the source and this
42file though; every change you make to the .c file should be reflected
43here. */

1884the symbol, and then fills in a register in the real instruction.
1885
1886The LITERAL reloc, at the LDQ instruction, refers to the .lita
1887section symbol. The addend is ignored when writing, but is filled
1888in with the file's GP value on reading, for convenience, as with the
1889GPDISP_LO16 reloc.
1890
1891The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
1892It should refer to the symbol to be referenced, as with 16_GOTOFF,
1893but it generates output not based on the position within the .got
1894section, but relative to the GP value chosen for the file during the
1895final link stage.
1896
1897The LITUSE reloc, on the instruction using the loaded address, gives
1898information to the linker that it might be able to use to optimize
1899away some literal section references. The symbol is ignored (read
1900as the absolute section symbol), and the "addend" indicates the type
1901of instruction using the register:
19021 - "memory" fmt insn
19032 - byte-manipulation (byte offset reg)
19043 - jsr (target of branch)
1905
1906The GNU linker currently doesn't do any of this optimizing. */
